1. A computer-program product comprising a non-transitory computer-readable storage medium having encoded therein computer-executable instructions for causing a computer to:
obtain performance data related to a performance of a broadband network; and provide a hierarchical display of network performance, the hierarchical display including a first level with first data indicative of network operation and a second level with second data indicative of a plurality of issues affecting the first level of network performance; wherein the second level includes multiple issues that contain a third level with third data indicative of contributing factors of the issues,
said instruction to provide a hierarchical display includes an instruction to obtain indicia of cumulative amounts of time that network elements of at least a desired portion of a broadband network were considered at each issue of the second level during a designated time frame; said computer executable instructions further comprising:
instructions to display the cumulative amounts in a hierarchy of network issues, the hierarchy including a summary category including summary values indicating total cumulative amounts of time the network elements in the at least a desired portion of the network were considered at corresponding issues, the hierarchy further comprising a plurality of sub-categories contributing to the summary category, and the sub-categories each further comprising at least one sub-sub-category contributing to the sub-categories, each issue being a predetermined threshold of modem hour quality;wherein the issues are classified as direct and indirect contributors to modem hour quality, the direct issues comprising cable modem resets, cable modem termination system resets, and downstream and upstream codeword error ratios, and indirect issues comprising upstream and downstream transmit and receive power and downstream and upstream signal to noise ratio, wherein a direct issue directly affects modem hour quality and an indirect issue directly affects a direct issue;
instructions for causing the computer to recommend action, regarding at least one of the network areas that are most-negatively contributing to network performance for improving network performance. |
